fyn can rig, though I’m sure I’m probably doing it horribly wrong. It’s a combination of rigging techniques learned in Lightwave and playing with the Armature modifier, with one tangent into using bendy bones (single bones with multiple segments) for the spine from the head down and then two bendy bones for neck and spine.
Had to put one more controller in to flex the spine in the right direction. The neck flexes one way (looking downward) fine but will not flex the other way (it’s jaggy in this pose, effects can be seen if you look carefully at the neck), adding another shape to control the flex like I did with the spine didn’t help and neither did my aforementioned tangent into bendy bones.
